Is compressed colchicine tablet superior to other colchicine preparations in patients with familial Mediterranean fever?

AIMS: The aim of our study is to evaluate the differences in effectiveness, dosage, and side effect profiles in the use of colchicine preparations and evaluate the superiority of compressed colchicine tablets in familial Mediterranean fever (FMF) patients with resistance or intolerance to coated colchicine tablets. MATERIALS AND METHODS: Patients who were diagnosed with FMF according to the Tel Hashomer criteria, aged 18 years and older, and switched from compressed colchicine to coated colchicine tablets in the rheumatology clinic of Gazi University were identified. The daily colchicine dose and FMF attack frequency before and after switching from coated colchicine tablets to compressed colchicine tablets were compared. RESULTS: The study included 43 female (72.9%) and 16 male patients (27.1%), and the mean age was 34.54 ± 8.3 years. The number of attacks per year was significantly reduced after switching to compressed colchicine tablets, and daily colchicine doses were lower after switching to compressed colchicine tablets (1.97 ± 0.23 vs 1.78 ± 0.39 mg, p < 0.001). CONCLUSION: Compressed colchicine tablets were shown to be superior to other colchicine preparations and compressed colchicine tablets to be a useful treatment option before initiating biological agents in patients who were unresponsive to coated colchicine.

Calcineurin inhibitors in unplanned pregnancies with active lupus disease: A retrospective observational study.

OBJECTIVES: To evaluate the use of calcineurin inhibitors (CNIs), specifically tacrolimus, in unplanned pregnancies with active lupus disease among patients with systemic lupus erythematosus (SLE). MATERIALS AND METHODS: The study includes data from pregnancies in women diagnosed with SLE at Gazi University Hospital in Ankara, Türkiye, between January 2010 and July 2022. The study categorized pregnancies into planned and unplanned groups based on lupus nephritis presence, emphasizing the need for inactive lupus disease for at least 6 months before attempting conception in planned pregnancies. The outcomes of pregnancies involving CNIs, particularly tacrolimus, were assessed. RESULTS: In our cohort comprising 632 SLE patients, 39 individuals reported 42 pregnancies. Among the 42 pregnancies, 14 have a history of lupus nephritis. We observed that 8 of 14 patients with a history of lupus nephritis had unplanned pregnancies. Three patients used cyclosporine and 2 used tacrolimus during their pregnancy; their pregnancies were completely healthy, and no lupus flare was observed during their pregnancies. The pregnancy of 2 patients who used azathioprine and 1 last patient who used no immunosuppressive treatment ended in abortion. CONCLUSION: This study reveals that tacrolimus can be effectively used in unplanned pregnancies with active lupus disease, providing favorable maternal and fetal outcomes. The findings emphasize the importance of considering CNIs, particularly tacrolimus, in the management of SLE pregnancies, even in cases of unplanned pregnancies with a history of lupus nephritis.

Effects of interleukin-1 antagonists on de novo and pre-existing damage in patients with familial Mediterranean fever.

OBJECTIVES: Colchicine is the mainstay of familial Mediterranean fever treatment and interleukin (IL-1) antagonists are the treatment of choice in resistant patients. We aimed to investigate efficacy of IL-1 antagonists in the prevention of damage, as well as the causes of treatment failure. METHODS: A total of 111 patients fulfilling Euro fever and Tel-Hashomer criteria and treated with IL-1 antagonists were included in the study. Patients were grouped according to their recent damage status: no damage, pre-existing damage and de novo damage that developed under IL-1 antagonist treatment. The degree of damage was determined using the Auto Inflammatory Disease Damage Index (ADDI). Total damage score was calculated separately as its original definition and with excluding chronic musculoskeletal pain, creating the modified ADDI (mADDI). RESULTS: Forty-six patients (43,2 %) had damage according to the mADDI. Damage was commonly observed at musculoskeletal, renal and reproductive domains. Median duration of treatment was forty-five months. Two patients developed de novo damage: one musculoskeletal and one reproductive in this time-period. Five patients had a worsening of their damage while using IL-1 antagonists. De novo damage with IL-1 antagonist treatment was associated with acute phase protein levels. CONCLUSIONS: We evaluated change in damage accrual while using IL-1 antagonists in patients with FMF. Physicians should pay attention to controlling inflammation to prevent further damage, especially in those with pre-existing damage.

COVID-19 in familial Mediterranean fever: Clinical course and complications related to primary disease.

OBJECTIVES: To evaluate the impact of familial Mediterranean fever (FMF) features on the clinical course and outcomes of coronavirus disease 2019 (COVID-19) and clinical course of FMF after COVID-19. METHODS: Consecutive FMF patients with COVID-19 were enrolled from three referral hospitals. Clinical features of FMF and detailed COVID-19 information were obtained from patient interviews and medical records. RESULTS: Seventy-three FMF patients were included in the study. 94.5% of patients had clinical symptoms of COVID-19. We found 24.7% hospitalization, 12.3% respiratory support, 4.1% intensive care unit admission, 6.8% complication, and 1.4% mortality rate in patients. The risk factors of hospitalization for respiratory support were male gender [OR: 7.167 (95% CI: 1.368-37.535)], greater age [OR: 1.067 (95% CI: 1.016-1.121)], and non-adherence to colchicine treatment before the infection [OR: 7.5 (95% CI: 1.348-41.722)]. One-third of patients had reported attacks after COVID-19. The patterns of triggered attacks were fever, peritonitis, pleuritis, transient arthritis, chronic knee mono-arthritis, and protracted febrile myalgia. CONCLUSIONS: FMF characteristics were not associated with worse outcomes of COVID-19. Colchicine non-adherence was the risk factor of hospitalization for oxygen support. The rate of FMF attacks after COVID-19 is prominently increased, with some of them being protracted and destructive.

Compliance of Familial Mediterranean Fever Patients With Regular Follow-up Visits and Associated Factors.

BACKGROUND: Follow-up is crucial to detect asymptomatic complications of familial Mediterranean fever (FMF). The current European League Against Rheumatism recommendations state that patients with FMF should be evaluated at least every 6 months to monitor attacks, acute phase response, and proteinuria. OBJECTIVES: This study aimed to assess compliance of FMF patients with regular follow-up visits and the associated factors. METHODS: Adult patients with a diagnosis of FMF who had their initial visit at least over 1 year ago were included. Demographic and socioeconomic data, family history, and comorbid diseases were obtained from medical records. The International Severity Score for FMF and the Autoinflammatory Disease Damage Index scores were calculated. We defined patients as "compliant with follow-up visits" both if they had at least 2 visits during the previous year and a compatible physician's assessment. The characteristics of the compliant and noncompliant patients were compared, and multivariable logistic regression analysis was used to determine the factors influencing visit compliance. RESULTS: Four hundred seventy-four patients with FMF were included. Two hundred thirty (48.5%) were compliant, and 244 (51.5%) were noncompliant with follow-up visits. A family history of FMF in parents, the absence of a family history of FMF in siblings, treatment with biologic agents, concomitant medication use, multisite involvement during FMF attacks, and treatment satisfaction were independent predictors of visit compliance. CONCLUSIONS: Only half of the patients with FMF were compliant with follow-up visits. Better strategies should be implemented to increase the compliance of FMF patients. Identifying independent predictors would help to build one.

Diagnostic utility of serum biomarkers in large vessel vasculitis and their correlation with positron emission tomography.

OBJECTIVES: To investigate the association between vascular inflammation, as detected by positron emission tomography (PET) imaging and interleukin-6 (IL-6), pentraxin3, and B-cell-activating factor (BAFF) in subjects with LVV. METHODS: The study included newly diagnosed giant cell arteritis (GCA, n = 27) or Takayasu arteritis (n = 9) patients and healthy control (HC, n = 31) subjects. PET scan and blood samples were obtained before the introduction of treatments. IL-6, PTX3, and BAFF levels were determined quantitatively by enzyme-linked immunosorbent assay kits. RESULTS: Thirty-six patients with LVV (20 females, 16 males; age 64.5 ± 16.6 years) and 31 HC (14 females, 17 males; age 37.1 ± 9.6 years) were included. Serum levels of IL-6, PTX3, and BAFF were increased in patients with newly diagnosed LVV compared with healthy control subjects. In receiver operating characteristics (ROC) analysis, serum IL-6 and BAFF provided excellent discrimination of newly diagnosed LVV patients from HC (area under the ROC curve of >0.90 and >0.80, respectively). None of the inflammatory markers correlated with vascular inflammatory activity determined by PET scanning. CONCLUSIONS: Our results suggest that IL-6 and BAFF may serve as markers of large vessel vasculitis, while PTX3 is not useful. None of the inflammatory markers correlated with PET assessed vasculitis activity.

Predictors of persistent inflammation in familial Mediterranean fever and association with damage.

OBJECTIVE: Persistent inflammation is an insidious and less studied feature of FMF. We investigated clinical determinants of persistent inflammation and its associations with individual damage items. METHODS: This is a cross-sectional analysis of 917 FMF patients, who fulfilled the Tel Hashomer criteria and had at least 6 months' follow-up. Patients were stratified based on whether they had persistent inflammation. We used logistic regression analysis to investigate independent predictors of persistent inflammation and the associated individual damage items. RESULTS: One hundred and forty-two (15%) patients had persistent inflammation. Active FMF (54%) was the most prominent reason for the persistent inflammation. Spondylarthritis (16%), other inflammatory arthritis (8%) and IBD (2%) were other frequent reasons. Male gender, history of exertional leg pain, inflammatory comorbidities, M694V homozygosity, colchicine resistance, lower education levels and musculoskeletal attack dominance were found to be the independent predictors of persistent inflammation. Earlier disease onset led to a tendency towards persistent inflammation. Patients with persistent inflammation were more likely to suffer damage. There is an increased risk of developing proteinuria, amyloidosis and renal insufficiency. CONCLUSION: We identified, for the first time, the predictors of persistent inflammation in adult FMF patients and related individual damage items of the Autoinflammatory Disease Damage Index. Persistent inflammation is insidious and one of the chief causes of damage; therefore, especially patients with these predictors should be followed up more closely. If detected, underlying inflammatory comorbidities should be assessed meticulously as early detection and proper treatment strategies may favourably impact the natural history of the disease.

The assessment of serum ACE activity in COVID-19 and its association with clinical features and severity of the disease.

Angiotensin-converting enzyme (ACE)/Angiotensin (Ang) II pathway has crucial regulatory effects on circulatory hemostasis and immune responses. This pathway has a major role in the development of acute lung injury and acute respiratory distress syndrome (ARDS), which is a devastating complication of SARS-CoV-2 infection. The aim of this study is to investigate the serum ACE activity and its correlation with clinical features and the disease severity in patients with COVID-19. Patients with confirmed COVID-19 by detecting SARS-CoV-2 nucleic acid RT-PCR were included in the study. Demographic data, clinical features, laboratory and radiologic investigations were recorded. Patients were classified by disease severity; asymptomatic, mild, and severe pneumonia. The serum ACE activity was evaluated with an autoanalyzer based on a spectrophotometric method. Fifty-five patients (50.9% female) and 18 healthy subjects (33.3 % female) were enrolled in the study. The median age of patients was 40 years, ranging from 22 to 81 years. Eighteen healthy subjects were served as the control group. The baseline characteristics were comparable between groups. The median serum ACE activity of patients and controls (38.00 [IQR 21] U/L and 32.00 [IQR 24] U/L, respectively) and of between patients grouped by disease severity (38.5 [IQR 19], 36 [IQR 25], and 38 [IQR 22] U/L, asymptomatic, mild and severe pneumonia group, respectively) were similar. There was no correlation between the serum ACE activity and conventional inflammatory markers. In this study, we did not find an association between serum ACE activity and COVID-19 and serum ACE activity on admission did not reflect disease severity.

Diaphragmatic muscle thickness and diaphragmatic function are reduced in patients with systemic lupus erythematosus compared to those with primary Sjögren's syndrome.

INTRODUCTION: Systemic lupus erythematosus (SLE) is associated with an increased risk of pulmonary infections, as well as a rare condition known as shrinking lung syndrome (SLS). The diaphragm has an important role to play in lung physiology and might also play a role in these adverse events. Here, we aimed to investigate whether SLE patients have impairment in their diaphragmatic muscle thickness and function with respect to another connective-tissue disease: primary Sjögren's syndrome (pSS). METHOD: Patients diagnosed with SLE who were in remission or who had minimal disease activity and had at least one year of follow-up were included in this study. Patients with known lung pathology and smokers were excluded. Patients with pSS constituted the second experimental group. Ultrasonographic evaluation of the diaphragmatic muscle was conducted by an experienced independent sonographer at three time points, diaphragmatic thickness during deep and quiet inspiration and maximum expiration being measured. Diaphragmatic muscle function was evaluated with maximum expiratory pressure (MEP) and maximum inspiratory pressure (MIP). RESULTS: A total of 115 patients were studied (n = 39 SLE; n = 76 pSS). The mean ± standard deviation (SD) thickness of the diaphragmatic muscles during quiet inspiration was significantly reduced in patients with SLE compared to patients with pSS (2.32 mm vs. 2.81 mm; p < 0.05). Similarly, the thickness during deep inspiration and at maximum deep expiration were significantly lower in SLE patients (2.88 mm vs. 3.29 mm and 1.92 mm vs. 2.33 mm, respectively; p < 0.01). MIPs and MEPs, defined as the percentages of expected values, were significantly lower in patients with SLE compared to those with pSS (80% vs. 92% and 76% vs. 120%, respectively; p < 0.05). Diaphragmatic muscle thickness during deep inspiration demonstrated a moderate correlation with MIP (r = 0.434; p = 0.001). CONCLUSION: SLE patients had reduced diaphragmatic muscle thickness compared to those with pSS, which was associated with impaired functional tests. Further prospective studies are needed to investigate whether structural and functional impairments in diaphragmatic muscle play a role in an increased risk of pulmonary infections and SLS in patients with SLE.

Factors associated with damage in patients with familial Mediterranean fever.

OBJECTIVES: Defining predictors of damage would improve patient care. We applied damage indexes to patients with familial Mediterranean fever (FMF) and identified the predictors of damage. METHODS: This is a cross-sectional analysis of 926 FMF patients, who fulfilled the Tel-Hashomer criteria and had at least six months of follow-up. Patients were stratified according to their damage status (damage vs. no damage) defined with autoinflammatory disease damage index (ADDI) and modified ADDI (excluding musculoskeletal pain). We used logistic regression analysis to investigate independent predictors of damage for both indexes. RESULTS: Mean disease duration was 21.6±11.9 years. 527 patients (57%) had damage according to ADDI. Median ADDI score was 1 (0-11). Most common FMF-related damages were observed in musculoskeletal, reproductive and kidney domains. Female gender, inflammatory comorbidity, colchicine resistance, colchicine nonadherence, musculoskeletal attack dominance, diagnostic delay, follow-up time, and smoking history remained independent predictors of damage according to ADDI score. The rate of patients with damage defined by modified ADDI was only to 23%. M694V/M694V homozygosity, female gender, musculoskeletal attack dominance, colchicine resistance, persistent inflammation, follow up time and family history of amyloidosis were found to be predictors of damage according to modified ADDI score. CONCLUSIONS: Our study is the first to apply comprehensive damage indexes to FMF patients and identified predictors of damage. Factors linked to a severe FMF phenotype, including M694V homozygosity and persistent inflammation, were associated with only modified ADDI. Our findings justify the concerns about musculoskeletal pain and might point to the need for re-evaluation of ADDI for FMF patients.

COVID-19, immune system response, hyperinflammation and repurposing antirheumatic drugs

In the Wuhan Province of China, in December 2019, the novel coronavirus 2019 (COVID-19) has caused a severe involvement of the lower respiratory tract leading to an acute respiratory syndrome. Subsequently, coronavirus 2 (SARS-CoV-2) provoked a pandemic which is considered a life-threatening disease. The SARS-CoV-2, a family member of betacoronaviruses, possesses single-stranded positive-sense RNA with typical structural proteins, involving the envelope, membrane, nucleocapsid and spike proteins that are responsible for the viral infectivity, and nonstructural proteins. The effectual host immune response including innate and adaptive immunity against SARS-Cov-2 seems crucial to control and resolve the viral infection. However, the severity and outcome of the COVID-19 might be associated with the excessive production of proinflammatory cytokines "cytokine storm" leading to an acute respiratory distress syndrome. Regretfully, the exact pathophysiology and treatment, especially for the severe COVID-19, is still uncertain. The results of preliminary studies have shown that immune-modulatory or immune-suppressive treatments such as hydroxychloroquine, interleukin (IL)-6 and IL-1 antagonists, commonly used in rheumatology, might be considered as treatment choices for COVID-19, particularly in severe disease. In this review, to gain better information about appropriate anti-inflammatory treatments, mostly used in rheumatology for COVID-19, we have focused the attention on the structural features of SARS-CoV-2, the host immune response against SARS-CoV-2 and its association with the cytokine storm.

Calcinosis in systemic sclerosis: An update on pathogenesis, related complications, and management: A heavy burden still waiting to be lifted off patients' hands.

In SSc, dystrophic calcinosis is one of the major clinical manifestations, characterized by the deposition of insoluble calcific substances in tissues, predominantly in the chemical form of calcium hydroxyapatite. Furthermore, calcinosis might lead to compressive neuropathies and severe pain. Current evidence suggests that tissue ischemia and repeated trauma are implicated in the development of calcinosis; however, there are still too many unknown areas that need to be investigated. Detection of calcinosis is commonly performed using X-ray or ultrasound. Moreover, quantification of calcinosis with X-ray and dual-energy computed tomography might be useful for the assessment of disease burden and monitoring of the disease. Despite its prevalence and clinical outcomes, there are no approved disease-modifying treatments for calcinosis in SSc. Debulking or surgical intervention might be preferred for calcinosis complicated with infection, compressive symptoms, or relief of pain. Therefore, innovative investigations and tailored therapeutic approaches are urgently needed to lift the burden of calcinosis from the hands of SSc patients.

Colchicine-intolerant familial mediterranean fever patients: A comparative study between different colchicine doses and IL-1 inhibitor monotherapy.

OBJECTIVE: Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease. Colchicine is the primary treatment for FMF, although some patients do not respond well or are unable to tolerate it. For these patients, the addition of interleukin-1 (IL-1) antagonists is the preferred option. However, the impact of colchicine treatment alongside the use of IL-1 antagonists remains unclear. METHODS: We recruited adult FMF patients who satisfied the Eurofever and Pediatric Rheumatology International Trials Organization classification criteria and were receiving IL-1 antagonist treatment from our FMF cohort. All the patients exhibited colchicine intolerance or resistance. As per the FMF cohort protocol, the patients were longitudinally followed up, including assessments of their C-reactive protein, erythrocyte sedimentation rate, autoinflammatory disease activity index (AIDAI), and autoinflammatory damage index (ADDI). RESULTS: Among the 125 patients (68 female and 57 male), 96 received a combination of IL-1 antagonists and the maximum tolerated dose of colchicine, whereas 29 were treated exclusively with IL-1 antagonists due to colchicine intolerance. The patients' inflammatory markers, AIDAI activity, and ADDI damage scores did not differ significantly between the two groups during the follow-up period. Notably, the drug retention rates were significantly higher in the patients treated solely with IL-1 antagonists. CONCLUSION: While the typical approach is to maintain colchicine treatment alongside the use of IL-1 antagonists, for patients who cannot tolerate effective colchicine doses, IL-1 antagonists alone may effectively control FMF disease activity.

Validation of Turkish version of the Cochin 17-item Scleroderma Functional scale.

INTRODUCTION: The Cochin 17-item Scleroderma Functional (CSF-17) Scale is a patient-reported outcome measure evaluating activities and participation in patients with systemic sclerosis (SSc). OBJECTIVE: The aim of the present study was to translate and cross-culturally adapt the CSF-17 into the Turkish language and investigate its convergent validity and reliability in Turkish-speaking patients with SSc. METHODS: The CSF-17 was cross-culturally adapted according to Beaton's guideline. Participants completed CSF-17 Scale, Scleroderma Health Assessment Questionnaire (SHAQ), Short Form-12 (SF-12) Health Survey and Hospital Anxiety and Depression Scale (HADS). Internal consistency and test-retest reliability were determined interpreting Cronbach's alpha and Intraclass Correlation Coefficient (ICC) values, respectively. Convergent validity was tested using Pearson's correlation coefficient. RESULTS: Fifty-six patients with SSc were enrolled in the study. Cronbach's alpha and ICC values of the CSF-17 total score were found to be as 0.963 and 0.958, respectively, indicating excellent reliability. As for the convergent validity, it was determined that CSF-17 total score has a good correlation with SHAQ. Correlations of subscales of CSF-17 with subscales of SF-12 and HADS ranged from poor to moderate. CONCLUSION: Turkish version of CSF-17 met the set criteria of reliability and convergent validity. According to the results of the analysis, it was concluded that the Turkish version of the CSF-17 is a reliable and valid tool for Turkish-speaking SSc patients.

Determination of the Voice Parameters in Adult Individuals With Rheumatoid Arthritis and the Relation of Voice With Depression and Inflammation.

OBJECTIVES: To assess, through both objective and subjective methods, the complaints of dysphonia among adults with rheumatoid arthritis (RA). The secondary purpose of the study is to determine whether complaints of dysphonia are related to depression and disease activity. STUDY DESIGN: This is a prospective cohort study. METHODS: Eighty subjects (38 RA and 42 healthy volunteers aged 18-65 years old) were included in the study. Participants were evaluated using the Voice Handicap Index-10 (VHI-10) to assess voice complaints. Laryngeal findings of participants with RA were performed by videolaryngoscopy. Maximum phonation time (MPT) measurements and acoustic voice analysis (PRAAT software) were performed to evaluate the presence of objective dysphonia. Disease activity of individuals was calculated by using Disease Activity Score-28 (DAS-28) scale. Beck Depression Inventory (BDI) was applied to evaluate the symptoms of depression in participants. RESULTS: The prevalence of laryngeal symptoms of participants with RA was %42.1. According to the cut-off score of VHI-10, 15.8% of the participants in the study group had voice complaints. Comparing the MPT and acoustic voice analyses values of the study and control group, the MPT of the RA participants were statistically lower (P< 0.05). Perturbation parameters of male participants in the study and control groups were statistically different. 15.8% of participants in RA group had symptoms of depression. However, there was no statistically significant difference between BDI and acoustic voice parameters. CONCLUSIONS: RA may be associated with voice disorders. Male patients with RA had worse jitter parameters, but the number of participants was low. Dysphonia may not be associated with depression and disease activity in RA patients.

Treatment with biologic DMARDs may not adversely affect lung nodules in rheumatoid arthritis patients.

OBJECTIVE: Lung nodules (LNs) impose diagnostic and therapeutic challenges in patients with rheuma- toid arthritis (RA) due to unpredictable outcomes. Potential induction of nodulosis with the use of con- ventional synthetic DMARDs (csDMARD) and lack of knowledge regarding the effect of biologic disease-modifying anti-rheumatic drugs (bDMARDs)/tofacitinib on the LN raise concerns and have an impact on treatment decisions. This study aims to evaluate the possible effects of the bDMARDs/tofa- citinib and csDMARDS on LNs observed in RA patients. METHODS: Electronic health records of RA patients who had LNs detected on computed tomography (CT) between January 2015 and December 2020 were evaluated retrospectively. Patients with follow- up CT images were included in the study. Baseline and follow-up images were meticulously examined for the number, size, attenuation, and cavity formation. Clinical, histopathologic, and laboratory find- ings were analyzed. RESULTS: Forty-two RA patients with LNs were studied, 21 were on bDMARDs/tofacitinib (11 females, mean age: 59.7 6 8.4) and 21 were on csDMARDs (12 females, mean age: 71.4 6 8.3). The proportion of patients with progressed nodules during follow-up was comparable between groups (six patients in bDMARDs/tofacitinib vs seven patients in csDMARDs). Progression of LNs was observed in six patients in the bDMARDs/tofacitinib group: three in anti-TNFa, two in rituximab, and one in abatacept users and none in tofacitinib users. CONCLUSION: Our results suggest that the risk of progression in LNs in RA patients with use of bDMARDs/tofacitinib might not impose a higher risk compared to csDMARDs. Moreover, bDMARDs/ tofacitinib might result in regression in LNs.
